TECHNICAL FIELD

This invention relates to substituted aminotetrazoles analogues that are antagonists of P2X₇ receptors, and to the use of such compounds for treating conditions related to P2X₇ receptor activation.

BACKGROUND OF THE INVENTION

P2X receptors are ionotropic receptors activated by ATP. The importance of P2X receptors in nociception is underscored by the variety of pain states in which this endogenous ligand can be released. Of the seven P2X receptors, the P2X₇ is distinguished by its ability to form a large pore upon prolonged or repeated agonist stimulation. It is partially activated by saturating concentrations of ATP, whereas it is fully activated by the synthetic ATP analog benzoylbenzoic ATP (BzATP) (Bianchi et al., Eur. J. Pharmacol. Vol. 376, pages 127-138, 1999). The P2X₇ receptor is expressed by presynaptic terminals in the central and peripheral nervous systems, antigen-presenting cells including macrophages, human epidermal Langerhans' cells, microglial cells and a number of tumor cell lines of varying origin (Jacobson K A, et al. “Adenosine and Adenine Nucleotides: From Molecular Biology to Integrative Physiology”. L. Belardinelli and A. Pelleg (eds.), Kluwer, Boston, pages 149-166, 1995).

On glial cells, the P2X₇ receptor has been shown to mediate release of glutamate (Anderson C. et al. Drug Dev. Res. Vol. 50. page 92, 2000). Since glutamate is known to be involved in the neurotransmission of painful sensory signals, inhibition of P2X₇ may have therapeutic utility in the treatment of various pain states. Furthermore, oxidized ATP (oATP), a nonselective and irreversible P2X₇ antagonist, was recently reported to possess peripherally-mediated antinociceptive properties in inflamed rats (Dell'Antonio et al. Neuroscience Lett., Vol. 327, pages 87-90, 2002). Thus, P2X₇ antagonists may have utility in the treatment of a variety of pain states.

Recent data also suggested a possible role for P2X₇ receptor activation in neuroinflammation and neurodegeneration (Collo G. et al. Neuropharmacology, Vol. 36, pages 1277-1283, 1997). In the central nervous system, the P2X₇ receptor is predominately expressed by microglia, the resident macrophages of the brain. Recent studies indicate a role of the P2X₇ receptor in the generation of superoxide in microglia, and upregulation of P2X₇ receptors around β-amyloid plaques in a transgenic mouse model for Alzheimer's disease (Parvathenani et al., J. Biol. Chemistry, Vol. 278, pages 13300-13317, 2003) and in multiple sclerosis lesions from autopsy brain sections (Narcisse et al., Glia, Vol. 49, pages 245-258 (2005). Thus, P2X₇ antagonists may have utility in the treatment of neurodegenerative conditions including stroke and Alzheimer's disease.

Activation of the P2X₇ receptor on cells of the immune system (macrophages, mast cells and lymphocytes) leads to release of interleukin-1β (IL-1β), giant cell formation, degranulation, and L-selectin shedding. Compounds acting at the P2X₇ receptor may therefore have utility in the treatment of various disease states and conditions such as rheumatoid arthritis, osteoarthritis, psoriasis, allergic dermatitis, asthma, chronic obstructive pulmonary disease, airways hyper-responsiveness, septic shock, glomerulonephritis, irritable bowel disease, Crohn's disease, ulcerative colitis, atherosclerosis, growth and metastases of malignant cells, myoblastic leukaemia, diabetes, Alzheimer's disease, meningitis, osteoporosis, burn injury, ischemic heart disease, stroke and varicose veins.

Neuropathic pain is another type of pain different from pain involved with inflammatory or neurodegenerative conditions. Neuropathic pain is associated with any disorder affecting any segment of the nervous system. Common causes of neuropathic pain are, among others, alcoholism, amputation, cancer chemotherapy, diabetes, trigeminal neuralgia, HIV infection, multiple sclerosis, shingles and spine surgery. One of the most dramatic examples of neuropathic pain is called “phantom limb syndrome” which occurs when an arm or a leg have been removed, but the brain still gets pain messages from the missing limb.

A recent study reported the localization of P2X₇ on presynaptic terminals in the central and peripheral nervous systems (Deuchars et al J. Neuroscience, Vol. 21, p′7143-7152, 2001) where its activation was linked to release of the excitatory amino acid neurotransmitter glutamate. This finding indicates a role for the P2X₇ receptor in the process of neuronal synaptic transmission and therefore a potential role for P2X₇ antagonists as novel therapeutic tool to treat neuropathic pain.

Oxidized ATP (oATP), a nonselective and irreversible P2X₇ antagonist, was recently reported to possess peripherally mediated antinociceptive properties in inflamed rats (Dell'Antonio et al., Neuroscience Lett. Vol. 327, pages 87-90, 2002).

Studies from mice lacking P2X₇ receptor rsulted in absence of inflammatory and neuropathic hypersensitivity to mechanical and thermal stimuli, indicating a link between a P2X₇ purinoceptor gene and inflammatory and neuropathic pain (Chessell et al., Pain, Vol 114, pages 386-396 (2005)).

Antagonists to the P2X₇ receptor significantly improved functional recovery and decreased cell death in spinal cord injury (SCI) animal models. Rats with SCI were administered P2X₇ receptor irreversible antagonists oATP and PPADS with a resulting decrease of histological injury and improved recovery of motor function after the lesions (Wang et al., Nature Medicine Vol. 10, pages B21-B27, 2004).

In view of the above facts, there is a need for selective P2X₇ antagonist that can be efficiently used in preventing, treating, or ameliorating states as neuropathic pain, chronic inflammatory pain, inflammation and neurodegenerative conditions associated with several progressive CNS disorders, including, but not limited to, Alzheimer's disease, Parkinson's disease, depression, amyotrophic lateral sclerosis, Huntington's disease, dementia with Lewy bodies, multiple sclerosis as well as diminished CNS function resulting from traumatic brain injury.

This invention is intended to encompass compounds having Formula (I) or (II), when prepared by synthetic processes or by metabolic processes. Preparation of the compounds of the invention by metabolic processes includes those occurring in the human or animal body (in vivo) or processes occurring in vitro.

The compounds of the invention can comprise asymmetrically substituted carbon atoms known as chiral centers. These chiral centers are designated as “R” or “S” depending on the configuration of substituents around the chiral carbon atom. The terms “R” and “S” used herein are configurations as defined in IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem., 1976, 45: 13-30. The compounds of this invention may exist as single stereoisomers (e.g., single enantiomers or single diastereomer), mixtures of stereoisomers (e.g. any mixture of enantiomers or diastereomers) or racemic mixtures. All such single stereoisomers, mixtures and racemates are intended to be encompassed within the scope of the invention. Compounds identified herein as single stereoisomers are meant to describe compounds that are present in a form that are substantially free from their enantiomers or other diastereomers. By “substantially free” is meant greater than about 80% free of other enantiomers or diastereomers of the compound, more preferably greater than about 90% free of other enantiomers or diastereomers of the compound, even more preferably greater than about 95% free of other enantiomers or diastereomers of the compound, even more highly preferably greater than about 98% free of other enantiomers or diastereomers of the compound and most preferably greater than about 99% free of other enantiomers or diastereomers of the compound. Where the stereochemistry of the chiral carbons present in the chemical structures illustrated herein is not specified, the chemical structure is intended to encompass compounds containing either stereoisomer of each chiral center present in the compound.

Individual stereoisomers of the compounds of this invention can be prepared by any one of a number of methods which are within the knowledge of one of ordinary skill in the art. These methods include stereospecific synthesis, chromatographic separation of diastereomers, chromatographic resolution of enantiomers, conversion of enantiomers in an enantiomeric mixture to diastereomers and then chromatographically separating the diastereomers and regeneration of the individual enantiomers, enzymatic resolution and the like.

Stereospecific synthesis involves the use of appropriate optically pure (enantiomerically pure) or substantial optically pure materials and synthetic reactions which do not cause racemization or inversion of stereochemistry at the chiral centers. Mixtures of stereoisomers of compounds, including racemic mixtures, resulting from a synthetic reaction can often be separated by chromatographic techniques which are well-known to those of ordinary skill in the art.

Chromatographic resolution of enantiomers can be accomplished on chiral chromatography resins. Chromatography columns containing chiral resins are commercially available. In practice, the racemate is placed in solution and loaded onto the column containing the chiral stationary phase. The enantiomers are then separated by HPLC.

Resolution of enantiomers can also be accomplished by converting the enantiomers in the mixture to diastereomers by reaction with chiral auxiliaries. The resulting diastereomers can then be separated by column chromatography or crystallization/re-crystallization. This technique is especially useful when the compounds to be separated contain a carboxyl, amino or hydroxyl group that will form a salt or covalent bond with the chiral auxiliary. Chirally pure amino acids, organic carboxylic acids or organosulfonic acids are especially useful as chiral auxiliaries. Once the diastereomers have been separated by chromatography, the individual enantiomers can be regenerated. Frequently, the chiral auxiliary can be recovered and used again

Enzymes, such as esterases, phosphatases and lipases, can be useful for resolution of derivatives of the enantiomers in an enantiomeric mixture. For example, an ester derivative of a carboxyl group in the compounds to be separated can be prepared. Certain enzymes will selectively hydrolyze only one of the enantiomers in the mixture. Then the resulting enantiomerically pure acid can be separated from the unhydrolyzed ester.

Alternatively, salts of the enantiomers in the mixture can be prepared by any suitable method known in the art, including treatment of the carboxylic acid with a suitable optically pure base such as, but are not limited to, alkaloids and phenethylamine, followed by precipitation or crystallization/re-crystallization of the enantiomerically pure salts. Methods mentioned herein above and other useful methods for the resolution/separation of a mixture of stereoisomers, including racemic mixtures, may be found in “Enantiomers, Racemates, and Resolutions,” J. Jacques et al., 1981, John Wiley and Sons, New York, N.Y., the disclosure of which is incorporated herein by reference.

The compounds of this invention may possess one or more unsaturated carbon-carbon double bonds. All double bond isomers, both the cis (Z) and trans (E) isomers, and mixtures thereof are intended to be encompassed within the scoped of the present invention. Where a compound exists in various tautomeric forms, a recited compound is not limited to any one specific tautomer, but rather is intended to encompass all tautomeric forms.

The term “therapeutically acceptable salt” or “pharmaceutically acceptable salt” is intended to describe a salt or zwitterions of a compound of the invention and retains the biological effectiveness of the free acid or base of the specified compound without undue toxicity, irritation, and allergic response, commensurate with a reasonable benefit/risk ratio, effective for their intended use and is not biologically or otherwise undesirable; and as used herein, the term “therapeutically acceptable salt” or “pharmaceutically acceptable salt” refers to salts that are well known in the art. For example, S. M Berge et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 66:p 1-19, 1977).

The invention also relates to acid addition salts of Formula (I) or Formula (II). If an inventive compound contains a basic moiety a desired salt may be prepared by any suitable method known in the art, including treatment of the free base with an inorganic acid such as, but are not limited to, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, and phosphoric acid, or with an organic acid such as, but are not limited to, acetic acid, trichloroacetic acid, trifluoroacetic acid, maleic acid, succinic acid, mandelic acid, furmaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, pyranosidyl acid such as glucuronic acid or galacturonic acid, alpha-hydroxy acid such as citric acid or tartaric acid, amino acid such as aspartic acid or glutamic acid, aromatic acid such as benzoic acid or cinnamic acid, sulfonic acid such as p-toluenesulfonic acid, methanesulfonic acid, ethanesulfonic acid or the like. Examples of therapeutically acceptable salts include acetates, acrylates, adipates, alginates, aspartates, benzenesulfonates, benzoates, bisulfates, bisulfites, bromides, butyne-1,4-dioates, butyrates, camphorates, camphorsulfonates, caproates, caprylates, chlorides, chlorobenzoates, citrate, decanoates, digluconate, dinitrobenzoates, formates, fumarates, glutamates, glycerophosphate, glycollates, hemisulfate, heptanoates, hexanoates, hexyne-1,6-dioates, hydroxybenzoates, γ-hydroxybutyrates, iodides, isethionate, isobutyrates, lactates, mandelates, malonates, maleates, methanesulfonates, methoxybenzoates, methylbenzoates, naphthylenesulfonate, nicotinates, oxalates, pamoates, pectinates, persulfates, phenylacetates, phenylbutrates, phenylpropionates, phthalates, phosphates, picrates, pivalates, propanesulfonates, propionates, propiolates, p-toluenesulfonates, pyrosulfates, sebacates, suberates, succinates, sulfates, sulfites, tartrates, trichloroacetates, trifluoroacetates, undecanoates, and the like. Also, the basic nitrogen-containing groups can be quaternized with such agents as acids such as hydrochloric acid, hydrobromic acid, trifluoroacetic acid or acetic acid, loweralkyl halides, such as methyl, ethyl, propyl, and butyl chloride, bromides, and iodides; dialkyl sulfates like dimethyl, diethyl, dibutyl, and diamyl sulfates, long chain halides such as decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides, aralkyl halides like benzyl and phenethyl bromides, and others.

Such a desired salt may be prepared by any suitable method known to the art, including treatment of the free acid with an inorganic or organic base, such as amine (primary, secondary, or tertiary), an alkali metal or alkaline earth metal hydroxide, carbonates, bicarbonates or the like. Illustrative examples of suitable salts include organic salts derived from amino acids such as glycine and arginice, ammonia, primary, secondary, and tertiary amines, and cyclic amines, such as ethylene diamine, dicyclohexylamine, ethanolamine, piperidine, morpholine, and peperazine, as well as inorganic salts derived from sodium, calcium, potassium, magnesium, manganese, iron, copper, zinc, aluminum, and lithium.

In addition, solvates of the compounds of Formula (I) or Formula (II) are meant to be included in this invention. The term “solvate” is intended to mean a pharmaceutically acceptable solvate form of a specified compound that retains the biological effectiveness of such compound. Examples of solvates include compounds of the invention in combination with water, isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid, or ethanolamine. In the case of compounds, salts, or solvates that are solids, it is understood by those skilled in the art that the inventive compounds, salts, or solvates may exist is different crystal forms, all of which are intended to be within the scope of the present invention.

This invention also encompasses pharmaceutical compositions containing and methods of treating or preventing comprising administering prodrugs or salt of a prodrug of compounds having Formula (I) or Formula (II). The term “prodrug” are considered to be any covalently bonded carriers which release the active parent drug of formula (I) or (II) in vivo metabolically or by solvolysis when such prodrugs is administered to a mammalian subject. Prodrugs of the compounds of formula (I) or (II) can be prepared by modifying functional groups present in the compounds in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compounds respectively. Examples of such modification include, but not limited to, treatment of a compound of formula (I) or (II), containing an amino, amido, or hydroxyl moiety with a suitable derivatising agent, for example, a carboxylic acid halide or acid anhydride, or treatment of a compound of formula (I) or (II) containing a carboxyl moiety, to an ester, amide, carbonates or carbamates, or conversion of a compound of formula (I) or (H), containing a carboxylic acid ester moiety to an enol-ester. Compounds of Formula (I) or (II) having free amino, hydroxyl or carboxylic groups can also be converted to prodrugs by peptide bond formation with an amino acid residue, or a polypeptide chain of two or more (e.g. two, three or four) amino acid residues. The amino acid residues include the 20 naturally occurring amino acids commonly designated by three letters symbols and also include, 4-hydroxyproline, hydroxylysine, demosine, isodemosine, 3-methylhistidine, norvalin, beta-alanine, gamma-aminobutyric acid, citrulline, homocysteine, homoserine, ornithine and methionine sulfone.

Examples of prodrugs include, but are not limited to, acetate, formate, and benzoate derivatives of the hydroxy, carboxy and amine functional groups in the compounds of formula (I) or (II). A thorough discussion is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, V. 14 of the A.C.S. Symposium Series, and in Edward B. Roche, ed., Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987, hereby incorporated by reference.

In accordance with methods of treatment and pharmaceutical compositions of the invention, the compounds of formula (I) or (II), or therapeutically acceptable salt, solvate, prodrug or salt of a prodrug thereof, can be administered alone or be administered in the form of a pharmaceutical composition in which the compound of Formula (I) or Formula (II), or a therapeutically acceptable salt, solvate, prodrug, salt of a prodrug, or combination thereof, in combination with a pharmaceutically acceptable carriers, adjuvants, diluents, vehicles, or combinations thereof.

The term “pharmaceutically acceptable carrier, adjuvants, diluents or vehicles” as used herein, means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as lactose, glucose and sucrose; starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols; such a propylene glycol; esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.

The pharmaceutical compositions of this invention can be formulated in a conventional manner using one or more of the aforementioned pharmaceutically acceptable carriers. Thus the compounds of the present invention, its therapeutically acceptable salt, solvate, prodrug, salt of its prodrug, may be administered to humans and other mammals in solid or liquid form, orally, rectally, parenterally, intracisternally, intravaginally, topically (as by powders, ointments, drops, inhalants, spray, transdermal patch, and the like), or bucally. The term “parenterally,” as used herein, refers to modes of administration which include intravenous, intramuscular, intraperitoneal, intrasternal, subcutaneous, intraarticular injection and infusion.

Pharmaceutical compositions of this invention for parenteral injection comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (propylene glycol, polyethylene glycol, glycerol, and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity may be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

These compositions may also contain adjuvants such as preservative agents, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form may be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

In some cases, in order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle. Suspensions, in addition to the active compounds, may contain suspending agents, as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, tragacanth, and mixtures thereof.

If desired, and for more effective distribution, the compounds of the present invention can be incorporated into slow-release or targeted-delivery systems such as polymer matrices, liposomes, and microspheres. They may be sterilized, for example, by filtration through a bacteria-retaining filter or by incorporation of sterilizing agents in the form of sterile solid compositions, which may be dissolved in sterile water or some other sterile injectable medium immediately before use.

The active compounds can also be in micro-encapsulated form, if appropriate, with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound can be admixed with at least one inert diluent such as sucrose, lactose, or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of such composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes.

Injectable depot forms are made by forming microencapsulated matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides) Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.

The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use.

Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic, parenterally acceptable diluent or solvent such as a solution in 1,3-butariediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.

Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid; b) binders such as carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia; c) humectants such as glycerol; d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; e) solution retarding agents such as paraffin); f) absorption accelerators such as quaternary ammonium compounds; g) wetting agents such as cetyl alcohol and glycerol monostearate;) absorbents such as kaolin and bentonite clay; and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

Determination of Biological Activity

Tissue Culture:

Cells of the THP-1 monocytic cell line (American Type Culture Collection, Rockville, Md.) were maintained in the log phase of growth in RPMI medium containing high glucose and 10% fetal calf serum (Invitrogen, Carlsbad, Calif.) according to established procedures (Humphrey B D and Dubyak G R (1996), Induction of the P2z/P2X7 Nucleotide Receptor and Associated Phospholipase D Activity by Lipopolysaccharide and IFN-γ in the Human THP-1 Monocytic Cell Line. J. Immunology 157:5627-37). Fresh vials of frozen THP-1 cells were initiated for growth every eight weeks. To differentiate THP-1 cells into a macrophage phenotype, a final concentration of 25 ng/ml of lipopolysaccharide (LPS) and 10 ng/ml of IFNγ were added to the cells either for 3 hours for IL-1β release assays or overnight (16 hours) for pore formation studies.

P2X₇ Mediated Pore Formation.

Activation of the P2X₇ receptor induces nonspecific pore formation and eventually cell lysis (Verhoef et al., The Journal of Immunology, Vol. 170, pages 5728-5738, 2003). Accordingly, the inhibitory activity of the antagonists of the present invention was determined by their capacity to inhibit the agonist-induced pore formation using the fluorescent dye YO-PRO (MW=629) and Fluorometric Imaging Plate Reader (FLIPR, Molecular Devices, Sunnydale, Calif.). Prior to YO-PRO dye addition, the cells were rinsed once in PBS without Mg²⁺ or Ca²⁺ ions, which have been shown to inhibit pore formation (Michel et al., N-S Arch Pharmacol 359:102-109, 1999). The YO-PRO iodide dye (1 mM in DMSO) was diluted to a final concentration of 2 μM in phosphate buffered saline (PBS without Mg²⁺ or Ca²⁺) and then placed on the cells prior to the addition of the agonist BzATP. Since the THP-1 cells are a non-adherent cell line, the cells were washed in PBS and loaded with the dye in a conical tube prior to spinning the cells onto poly-lysine-coated black-walled 96-well plates, which were utilized to reduce light scattering. After the addition of the agonist BzATP (50 μM, the EC₇₀ value for agonist activation), the YO-PRO dye uptake was observed in the FLIPR apparatus equipped with an Argon laser (wavelength=488 nm) and a CCD camera. The intensity of the fluorescence was captured by the CCD camera every 15 seconds for the first 10 minutes of agonist exposure followed by every 20 seconds for an additional 50 minutes with the data being digitally transferred to an interfaced PC. The exposure setting of the camera was 0.25 sec with an f-stop setting of 2. Solutions of antagonist compounds were prepared by serial dilutions of a 10 mM DMSO solution of the antagonist into the buffer solution with the YO-PRO dye. Antagonist compounds were tested for activity over a concentration range from 0.003 to 100 μM. The test compounds were incubated for 10 minutes with the THP-1 cells at room temperature, after which the cells were stimulated with BzATP and fluorescence measured as described above in the absence of the antagonist. For antagonist activity measurements, the percent maximal intensity was normalized to that induced by 50 μM BzATP and plotted against each concentration of compound to calculate IC₅₀ values and account for plate-to-plate variability.

The potency of the compounds was inversely proportional to their IC₅₀ value. Representative compounds of the present invention when tested with the above assay demonstrated antagonist activity at the P2X₇ receptor.

P2X₇ Mediated IL-1β Release:

Activation of P2X7 receptors also induces secretion of IL-1β (Verhoef et al., above; Brough et al., Molecular and Cellular Neuroscience, Vol. 19, pages 272-280, 2002). THP-1 cells were plated in 24-well plates at a density of 1×10⁶ cells/well/ml. On the day of the experiment, cells were differentiated with 25 ng/ml LPS and 10 ng/ml final concentration of γIFN for 3 hours at 37° C. Solutions of antagonist compounds were prepared by serial dilutions of a 10 mM DMSO solution of the antagonist into the PBS solution. In the presence of the differentiation media, the cells were incubated with the antagonists of the present invention for 30 minutes at 37° C. followed by a challenge with 1 mM BzATP for an additional 30 minutes at 37° C. Supernatants of the samples were collected after a 5 minute centrifugation in microfuge tubes to pellet the cells and debris and to test for mature IL-1β released into the supernatant using either R & D Systems Human IL-1β ELISA assay or Endogen Human IL-1β ELISA, following the manufacturer's instructions. The maximum IL-1β release at each concentration of test compound was normalized to that induced by BzATP alone to determine the activity of the test compound. Antagonist compounds were tested for activity over a concentration range from 0.001 to 100 μM. Antagonist potency was expressed as the concentration producing a 50% reduction in release of IL-1β or IC₅₀. For each experiment, differentiated control cells were also measured over the 60 min time course of the assay to assess background IL-1β accumulation. This non-specific background IL-1β release, typically averaged 3-8% of the maximum BzATP response, was subtracted from the maximum BzATP-induced release and all release values normalized to the BzATP-induced response. Representative compounds of the present invention when tested with the above assay demonstrated antagonist activity at the P2X₇ receptor.

For all in vitro experiments, compounds of the present invention had IC₅₀ lower than 10 μM, preferably lower than 0.5 μM, and most preferably lower than 0.05 μM.

Determination of Analgesic Activity

Adult male Sprague-Dawley rats (250-300 g), Charles River Laboratories, Portage, Mich. were used in this study. Animal handling and experimental protocols were approved by the Institutional Animal Care and Use Committee (IACUC) at Abbott Laboratories. For all surgical procedures, animals were maintained under halothane anesthesia (4% to induce, 2% to maintain), and the incision sites were sterilized using a 10% povidone-iodine solution prior to and after surgeries.

Spinal Nerve Ligation:

A model of spinal nerve ligation-induced neuropathic pain was produced using the procedure originally described by Kim and Chung (Kim and Chung, Pain, Vol. 50 pages 355-363, 1992). The left L5 and L6 spinal nerves of the rat were isolated adjacent to the vertebral column and tightly ligated with a 5-0 silk suture distal to the DRG, and care was taken to avoid injury of the L4 spinal nerve. Sham rats underwent the same procedure, but without nerve ligation. All animals were allowed to recover for at least 1 week and not more than 3 weeks prior to assessment of mechanical allodynia. Mechanical allodynia in the left hind paw was confirmed by comparing the paw withdrawal threshold in grams for the injured left paw and the uninjured right paw. Mechanical allodynia was measured using calibrated von Frey filaments (Stoelting, Wood Dale, Ill.). Rats were placed into inverted individual plastic containers (20×12.5×20 cm) on top of a suspended wire mesh grid, and acclimated to the test chambers for 20 min. The von Frey filaments were presented perpendicularly to the plantar surface of the selected hind paw, and then held in this position for approximately 8 sec with enough force to cause a slight bend in the filament. Positive responses included an abrupt withdrawal of the hind paw from the stimulus, or flinching behavior immediately following removal of the stimulus. A 50% withdrawal threshold was determined using an up-down procedure (Dixon, Ann. Rev. Pharmacol. Toxicol., Vol. 20, pages 441-462, 1980). Prior to compound administration, animals demonstrating motor deficit or failure to exhibit subsequent mechanical allodynia were excluded from further studies. The antinociceptive activity of a test compound was determined by comparing its ability to increase the paw withdrawal threshold of the injured left paw relative to vehicle (0%) and the uninjured right paw (100%). Activity of test compounds was determined 60 minutes after an oral dose or 30 minutes after an intraperitoneal dose. Dose-response curves as well as single dose responses were performed. Representative compounds of the present invention exhibited antinociceptive activity in this assay.

C Freund's Adjuvant-Induced Thermal Hyperalgesia:

Unilateral inflammation was induced by injecting 150 μl of a 50% solution of complete Freund's adjuvant (CFA) (Sigma Chemical Co., St. Louis, Mo.) in physiological saline into the plantar surface of the right hindpaw of the rat. The hyperalgesia to thermal stimulation was determined 48 hr after CFA injections using a commercially available paw thermal stimulator (UARDG, Department of Anesthesiology, University of California, San Diego, La Jolla, Calif.). Rats were placed individually in Plexiglass cubicles mounted on a glass surface maintained at 30° C., and allowed a 30 min habituation period. A thermal stimulus, in the form of radiant heat emitted from a focused projection bulb, was then applied to the plantar surface of each hind paw. The stimulus current was maintained at 4.5 Amp and the maximum time of exposure was set at 20 sec to limit possible tissue damage. In each test session, each rat was tested in 3 sequential trials at approximately 5 min intervals. Paw withdrawal latencies were calculated as the mean of the two shortest latencies. The antinociceptive activity of a test compound was determined by comparing its ability to increase the paw withdrawal threshold of the injured right paw relative to vehicle (0%) and the uninjured left paw (100%). Activity of test compounds was determined 60 minutes after an oral dose or 30 minutes after an intraperitoneal dose. Dose-response curves as well as single dose responses were performed. Representative compounds of the present invention exhibited antinociceptive activity in this assay.

Zymosan Method:

Mice were dosed with experimental compounds orally or subcutaneously 30 minutes prior to injection of zymosan. Mice were then injected intraperitonealy with 2 mgs/animal of zymosan suspended in saline. Four hours later the animals were euthanized by CO₂ inhalation and the peritoneal cavities lavaged with 2×1.5 mL of ice cold phosphate buffered saline containing 10 units of heparin/mL. For IL-1β determination the samples were spun at 10,000×g in a refrigerated microfuge (4° C.), supernatants removed and frozen until ELISAs (Enzyme Linked Immuno-Assay) were performed. ELISAs were performed according to manufacture's instructions. IL-1β was determined relative to vehicle control. Representative compounds of the invention demonstrated inhibition of IL-1β release in a dose-dependent fashion. (Perretti M, Solito E, Parente L, Agents Actions Vol. 35(1-2) pages 71-78, 1992; Torok K, Nemeth K, Erdo F, Aranyi P, Szekely, J I, Inflamm Res. Vol. 44(6) pages 248-252, 1995.). Representative compounds of this invention exhibited inhibition of IL-1β release in this assay.

For all in vivo experiments, the compounds of the present invention had ED50 lower than 500 μmol/kg, preferably 50 μmol/kg.

To an oven-dried, 250-mL, round-bottomed flask containing a magnetic stir bar were added 2-chloro-5-fluoro-nicotinic acid (4.39 g, 25.0 mmol) and anhydrous toluene (50 mL). Thionyl chloride (5.95 g, 3.65 mL, 50 mmol) was added, and a reflux condenser with N₂-inlet was attached. A heating mantle was applied and the solution was heated to reflux for 2 hours. After cooling to room temperature, the solvent/volatiles were removed by rotary evaporator to give a golden oil. The crude acid chloride was added to a cold (0° C.) solution of ammonium hydroxide, and a white precipitate formed. The precipitate was collected by vacuum filtration on a glass frit and air dried.

To an oven-dried, 250 mL, round-bottomed flask were added the crude 2-chloro-5-fluoronicotinamide (1.05 g, 6.00 mmol) from above, anhydrous dichloromethane (25 mL), and triethylamine (2.12 g, 2.92 mL, 21.0 mmol). The flask was sealed with a septum and cooled to 0° C. in an ice bath. Neat trifluoroacetic anhydride (1.89 g, 1.25 mL, 9.00 mmol) was added slowly via syringe and the resulting solution was stirred at 0° C. for 30 minutes then allowed to warm to room temperature over 1 hour. Water (20 mL) was added, and the mixture was transferred to a separatory funnel. The mixture was extracted with dichloromethane (3×20 mL). The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated by rotary evaporator to give a golden oil. The product was purified by flash chromatography (silica gel: 10% ethyl acetate, 90% hexanes—product Rf˜0.3) to give 862 mg (92%) of the title compound as a pale yellow solid. ¹H NMR (CDCl₃) δ 8.66 (dd, J=7.8, 3.0 Hz, 1H), 8.82 (d, J=2.7 Hz, 1H).

To an oven-dried, N₂-purged, 250-mL, round-bottomed flask containing a magnetic stir bar were added the commercially available 2-chloro-3-cyanopyridine (1.5 eq), the arylboronic acid or ester (1.0 eq), and dichlorobis(triphenylphosphine)pallalium(II) (0.05 eq). The flask was sealed with a septum and purged with N₂ atmosphere. Anhydrous dioxane (15 mL) and a N₂-sparged solution of cesium carbonate (3.0 eq) in water (15 mL) were added via syringe. The reaction mixture was heated to ˜90° C. in an oil bath and stirred for 2 hours. The reaction was monitored by LC-MS. After cooling to room temperature, the solvent/volatiles were removed in vacuo to give a thick brown oil. Water (25 mL) was added and the mixture was transferred to a separatory funnel. The mixture was extracted with ethyl acetate (4×10 mL). The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated by rotary evaporator to give a brown solid. The crude solid was purified by flash column chromatography (ISCO Combiflash) on a 120 g silica gel cartridge using 30% isocratic for one minutes, then 30%-100% ethyl acetate over 6 min, 50 mL/minute. The solvent was removed in vacuo to give the 2-aryl-nicotinonitrile.

General Procedure 4: Thiourea Formation.

To an argon-purged, thick-walled pressure vessel was added wet Raney nickel (˜500 mg). A solution of ammonia-saturated methanol (30 mL) was added, followed by the 2-aryl-nicotinonitrile (150 mmol) The vessel was inserted into a Parr shaker and was charged with 60 psi of H₂ gas. The mixture was shaken at room temperature under static H₂ pressure for 3 hours. The H₂ gas was vented and the vessel was purged with argon. The solids were removed by vacuum filtration through Celite® 545. The solvent/volatiles were removed by rotary evaporator to give the crude amine.

To an oven-dried, N₂-purged, 25-mL, round-bottomed flask containing a magnetic stir bar was added the arylisothiocyanate (1.0 eq) and anhydrous tetrahydrofuran (10 mL). The flask was sealed with a septum and purged with N₂ atmosphere. A solution of the crude amine (1.2 eq) in anhydrous tetrahydrofuran (2 mL) was added via syringe. The solution was stirred at room temperature overnight. Saturated aqueous sodium bicarbonate (10 mL) was added to quench. The mixture was transferred to a separatory funnel and extracted with dichloromethane (3×10 mL). The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated by rotary evaporator to give a tan solid. The product was purified by recrystallization from ethyl acetate/heptane, trituration with dichloromethane or flash column chromatography to give the thio urea.

General Procedure 5: Tetrazole Formation.

To a scintillation vial was added a solution of 0.16 M C-(6′-fluoro-[2,3′]bipyridinyl-3-yl)-methylamine in tetrahydrofuran (3 mL, 0.492 mmol) and arylisothiocyanate (0.117 g, 0.492 mmol). The vial was shaken 1 hour at room temperature. Sodium azide (0.096 g, 1.48 mmol) and triethylamine (0.26 mL, 1.85 mmol) were added, followed by a solution of 0.62 M mercury (II) chloride in tetrahydrofuran (1 mL, 0.625 mmol). A thick, white precipitate formed immediately upon addition of the mercury salt. The mixture was stirred at room temperature overnight and monitored by LC-MS. Ethyl acetate (5 mL) was added, and the solids were removed by vacuum filtration through a glass frit. The solvent was removed in vacuo and the residue was purified by flash column chromatography (ISCO Combiflash) on a 12 g silica gel cartridge using 10% isocratic for one minutes, then 10%-100% ethyl acetate over 6 min, 25 mL/minute. The solvent was removed in vacuo to give the tetrazole.

General Procedure 6: Suzuki Coupling
